Does SuperTech Conventional meet wss-m2c946-a

Only question I have is how do Dexos and Ford's wss-msc-946a compare on a spider chart? Dexos has the advantage in terms of volatility less than 13% limit to Ford's 15% limit. Other than that what are the advantages of Dexos approval over Ford's?? I bet that Ford's specification is a bit closer or surpasses Dexos in some performance metrics. The only Ford spec on the Lubrizol spider chart is quite close to Dexos. I do agree that if Motorcraft had the ACEA A1\B1 that it would be helpful indeed.

OK but that statement means nothing. In order to carry a specification it needs to list the specification on the container, not a blanket "Meets most major gm, chrysler and ford specs" in a personal email to one individual.

My experience has been that if an oil truly meets a specification they tend to advertise that information. Also in my experience when something doesn't carry a specification, the language you posted is what they use.

The Dexos certification is actually a step below the old GM4871M spec so Dexos is nothing really special. It only serves purpose to ensure the drivers are atleast using an acceptable oil and to pad their pockets with license fees.


Nope GMBoy Motorcraft can not meet DEXOS the NOAK is too high along with ash. Once again Motorcraft 5W30 in the American market is nothing but API SN/ISLAC GF-5 lubricant along with the rest of entry level Phillips products. This must be hard to understand because of wording "synthetic blend" on the label.

BTW.... Is Motorcraft available in synblend 0w20?


It does not matter BTW because WSS-M2C946-A is not a 0W20 spec. The question from the OP is in reference to 5W30 grade only. Thus Supertech conventional is equal to Motorcraft because both meet the exact same specs.
